Tunicate bulbs are some of the most familiar bulbs we come in contact with both in and out of our gardens.
Many underground plant structures are generally named bulbs. A definition of a bulb is a plant that incorporates its entire life cycle in an underground storage unit. Technically true bulbs are compressed stems surrounded by fleshy leaves acting as food storage organs. They are in the Monocot family of plants.

Bulbs can be further classified by looking at their various growth habits. Some of these “bulbs” are actually further classified as “true” bulbs, corms, tubers and rhizomes. Examples of these bulbs respectively are: narcissus, crocus, dahlia and canna.
True bulbs are represented by two classifications, tunicate and imbricate as represented by onions and lilies in that order.
Tunicate bulbs have a dry thin paperlike sheath surrounding them which helps to prevent them from drying and improves their storage capability. The basal base plate along with the tunicate sheath hold the bulb together. Roots emerge at the bottom of the basal plate.
We enjoy these bulbs both in the kitchen and in our gardens. Our cooking is enhanced by the addition of the tunicate bulbs of onions, garlic and shallots. The joyous colors in our early spring gardens are presented by our daffodils, tulips and hyacinths.
The term “bulb” is used by most people to refer to plants that have underground, fleshy storage structures. Only some of the plants commonly called bulbs actually are bulbs. The general definition of a bulb is any plant that stores its complete life cycle in an underground storage structure. These underground storage structures store nutrient reserves to ensure the plants’ survival.
Tubers, rhizomes, corms, and bulbs actually all serve the same purpose, just in a different way. They are each a storage unit for food that gives the plant the energy it needs to grow, bloom and complete its lifecycle each and every year.
The energy is created and stored by the foliage’s photosynthesis. You’ve probably heard that it’s important not to cut back the foliage after the bloom has died. That is because the leaves need to have time to absorb energy for next year’s bloom. Each storage system takes differing amounts of time to perform this task. Examples would be Alliums and Daffodils.
Bulbs or bulb-like plants are usually perennials. They have a period of growth and flowering. This is followed by a period of dormancy where they die back to ground level at the end of each growing season.
As with perennials, there are bulbs that are hardy in our climate and others that must be overwintered as house plants or placed in dormant storage.
Bulbs can be broken down into five types of storage structures. These include: true bulbs, corms, (stem) tubers, tuberous roots and rhizomes.
“Leeks and Pearl Onions” a graphite drawing by the Artist Mary Ahern
My Garden and my Art go side by side. Both require me to make aesthetic judgments about composition, scale, color, texture and style. When I’m deciding where to plant the flowers I’ve hauled home on my endless trips to the nurseries it doesn’t seem that much different to me then when I’m deciding how to compose them on a two-dimensional surface.
I think about what style I’m looking for, what colors will work together, whether the scale of the placement works for me. I think about the type of flower and texture of the leaves. I make decisions about the 3D composition of the garden much like the 2D composition decisions on a painting.
Anemone coronaria – Watercolor Painting also, available as a print.
The garden adds so many additional layers of complexity since the artwork is moving in time with nature, the seasons, the elements, and time. The painting remains caught in a moment.
Capturing that ephemeral moment is so gratifying to me in my Fine Art. I control it, unlike my Garden which is usually out of control.

Grape muscari, otherwise known as Grape Hyacinths live close to the ground. For years I never took much notice of them except for the little spots of brilliant purple that bounced so nicely against the bright yellow daffodils they bloomed along with in April.
Then I got down. Hands and knees down.
What a surprise! How intricate the little flowers are. Little bells dance around a central stem forming a small pyramid. This inflorescence changes shape as it ages and can be more and less tightly knit.
The individual purple doesn’t seem to change on each bell but the overall purple varies when viewed at a distance based upon the tightness of the overall flower.
I enjoyed these 4″ bulbs so much in my garden that I bought a bag of them from Costco one year and low and behold the next spring the flowers that bloomed were very different from my originals. They were more blue than purple and were more rounded than pyramidal.
So I googled Grape Muscari and found a world of cultivars I didn’t previously know existed. That’s one of the things that is so much fun about gardening. You are constantly in a learning mode. You are in for surprises every year and every season. The knowledge and information you acquire just keeps on growing, along with your garden.
So now I know that so far in my garden I have Muscari armeniacum and M. azureaum. Next year I’m sure to have more.
Digital Painting – “Grape Muscari”. Available in various sizes.
When I made my Digital Mixed Media Painting of my Grape Muscari I was careful to recreate the basal growth of the leaves. It would not have been accurate if I’d placed the leaves higher on the stem. The painting would have looked like a plant Frankenstein. As a Garden Artist, that is not what I’m trying to create.
You can view this Grape Muscari piece in my Store.
Isn’t that a fantastic name? Dicentra spectabilis. It just rolls out of your mouth in a lilting singsong kind of rhythm, doesn’t it? I love to say it quietly under my breath as I walk around my woodland garden in May. Not too loud so as to scare the birds and the neighbors (and myself for that matter.) I love their color pink. I have some white ones, but the pink ones are just so … Continue reading →
I have a number of varieties of White Daffodils growing in my garden but I don’t feel that I ever have enough. Since I am over run by squirrels I try to focus away from crocus and my beloved tulips. (After all, both my parents were born in Holland!) Squirrels consider the bulbs as an entrée and the flowers, if they arrive, as a delectable garnish but they leave my daffodils alone. The abundant shade … Continue reading →
My garden is often the source material for my Mixed Media Paintings. Though I am not a Photographer, I like to use my digital camera to record the progress and changes in my garden from day to day and year to year. Springtime is such a hectic time since I’m always late uncovering the perennial beds. These jolly yellow daffodils came up in my entry garden and I was lucky enough to catch the early … Continue reading →
